Failed Payment Recovery Calculator

Estimate how much subscription revenue you lose to failed card payments and what smarter retries would recover. The result updates as you type so you can compare scenarios quickly.

The method

How it is worked out

Lost = subscribers × fail rate × (1 − recovery) × price × 12
fail rate
Share of monthly charges declined
recovery
Share of declines eventually collected

Keep in mind

What it leaves out

  • Voluntary churnCancellations are a different problem.
  • Retry costsEach retry carries a small fee; usually trivial against the recovered revenue.

Use the calculator to compare scenarios rather than as a guaranteed forecast.

About the Failed Payment Recovery Calculator

Put a number on involuntary churn: subscribers lost because a card payment failed and was never recovered.

How it works and an example to tryShow less

How to use the result

Failed payments are subscribers times the failure rate. Lost customers are those not recovered by retries. Revenue lost is that count times price, annualised; lifetime value multiplies by the average customer lifetime.

Example to try

5,000 subscribers at £29 with an 8% failure rate and 40% recovery lose 240 customers a month. Lifting recovery to 70% saves 120 a month, about £42,000 of annual MRR.

    Mistakes worth avoiding

    • Counting failed payments as voluntary churn and blaming the product.
    • Retrying on the same day the card failed, when it is most likely to fail again.
    • Cancelling access on the first decline instead of warning the customer.
